This application aims to be a tool that helps people who carry out outdoor activities alone so that, in the event of an accident, the app can send an alert message to the phones that the user determines.
In order to work, when you activate the alarm, the app accesses the GPS positioning data, even when you leave the app in the background, in order to determine if there is displacement.
If the app does not detect displacement, it starts a 30-second countdown, which allows you to cancel the sending of the SMS. If it is not cancelled, the SMS are sent to the indicated telephone numbers.
It is NOT useful if:
—>There is NO displacement, since it uses the GPS to determine if there is movement or not.
—>There is NO mobile coverage. The application launches the alert messages by means of an SMS through the mobile network. So if there is no coverage, it won't work.
Take all these conditions into account. Remember that the app may not work for various reasons, so, in addition to its use, it is recommended to use other complementary security means and explain or indicate to other people the route you intend to take before starting your activity.
